[GTALUG] Btrfs?

I just (finally) looked up the features of Btrfs, and it sounds fantastic. Possibly ZFS-adjacent but without the nightmarish license problems? Am I missing something? It's in the kernel, but if it was that good, lots of distros would be defaulting to it ... and they're not. A couple have tried, but it hasn't taken off. Can someone fill me in with the details I'm missing? -- Giles https://www.gilesorr.com/ gilesorr@gmail.com
